Favorable climate for cotton cultivation

Ideal climate for farming cotton

  • Cotton can be grown in places wherever, at least 180-200 frost free days are available.
  • High humidity leads to rotting of cotton.
  • Cotton is discoloured due to high light intensity.

Temperature required for cotton

  • Optimum temperature for germination is 20-30°C. 
  • Germination will be delayed if the temperature is less than 18°C.
  • Under adequate soil moisture, cotton can withstand high temperatures of 43-45°C for short periods.

Cotton crop water requirements

  • Originally it is Kharif crop, but during the vegetative phase, moderate rainfall is good whereas in later stages heavy rains will affect the quality of cotton.
  • Water requirement – Equivalent to 650-750 mm of rainfall

Ideal soil for growing cotton

Soil type

  • Black cotton soil with good water holding capacity
  • Cotton is sensitive to excessive moisture and water logging.

Soil pH

  • Required range – 7.0 – 8.5
  • If pH is <6.0 add Lime
  • If pH is >8.5 add Gypsum
Seed Rate
Varieties
4 kg/acre
Hybrids
800 gram/acre

Seed treatment in cotton crop

Treat the cotton seeds with 

  • Imidacloprid – 4 ml

Instructions – Mix the above quantity in two liter of water for one kg of seeds. Deep the seeds in solution for 10 min & then shade dry for 15 min.

  • Carbendazim 2 gram

Instructions – treated seeds again treat with the thiram 2 gram for 1 kg of seeds. Apply it on seed by rubbing it on seed surface.

Land preparation for cotton farming

Land Preparation

  1. Ploughing method – Plough the land 1 or 2 times based on soil type.
  2. Mix the following in field, and keep it in open air for 10 days for proper decomposition – 
    1. FYM – 2 tons
    2. Composting Bacteria – 3kg
  3. Spread the above mixture over soil and run rotavator to the entire field making the soil as a fine tilth.

Bed Preparation

  1. Bed preparation- Prepare ridges and furrows 90 cm apart with the help of tractor.

Cotton farming: cotton sowing

  • Cotton sowing time: April to second week of May
  • Put 2 seeds per hill on ridges at 2-3 inch deep and then cover with soil

Cotton fertilizer management

  • For Varieties- 20:10:10 kg NPK per acre
  • At sowing apply-

    Urea- 22 kg

    Single Super Phosphate- 62 kg 

    Muriate of Potash- 17 kg

  • 45 Days after sowing- 11 Kg kg Urea
  • 45 Days after sowing– 11 kg Urea
  • For Hybrids- 32:16:16 kg NPK per acre.
  • At sowing apply-

    Urea- 35 kg 

    Single Super Phosphate- 99 kg 

    Muriate of Potash- 27 kg

  • 30 Days after sowing- 17 kg Urea
  • 45 Days after sowing- 17 kg Urea

Irrigation in cotton farming

  • Flood – At 10 to 12 days interval (based on rainfall)
  • Flowering, boll formation and boll development stage are critical stages for irrigation at which irrigation must be applied regularly (Based on rainfall)

Cotton farming and intercultural operations

  1. Gap filling- After 10 days put seeds in gaps where germination is not observed.

     OR

  • Raise seedlings in polythene bags of size 15 x 10 cm.
  • Fill the polythene bags with a mixture of FYM and soil in the ratio of 1:3.
  • Dibble one seed per bag on the same day when sowing is taken up in the field.
  • Provide water at regular intervals
  • On the 10th day of sowing, plant seedlings maintained in polythene bags, one in each of the gaps in the field 
  1. Thinning- 
  • After 30 days keep 1 healthy plant per hill
  • Cutting of tops – Cut the tip of main stem on 90 days after sowing to stop vegetative growth and facilitate growth of bolls.

  • To avoid flower and boll dropping spray 40ml Naphthalene acetic acid in 200 liter water per acre at flowering stage. 
  • Take second spray at 15-20 days after first spray.

Post-harvest care for cotton

  • Immediately after picking, dry the cotton in shade. If it is not dried immediately the colour will change which will lower the market value.
  • Do not dry the cotton under direct sun as the fibre strength and luster will be lost.
  • Spread a thin layer of dry sand on the ground and keep the cotton over it.
